Combined with a complicated floor layout project as engineering background, considering the vertical component deformation on floor stress influence, the distribution of stress and strain in the floor is inspected under vertical and horizontal combination loads. Based on the aid of dynamic elastic-plastic time history analysis, it can find out the weak parts of the floor, and modify it in the design.Keywords: complexity slab; boundary condition; stress condition; stress; reinforcement作者簡介：冀苗苗，碩士，一級注冊結(jié)構(gòu)工程師，Email：beitianzi@163.com。參考文獻(xiàn)［1］JGJ 3—2010 高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］.北京：中國建筑工業(yè)出版社，2011.［2］GB 50011—2010 建筑抗震設(shè)計(jì)規(guī)范［S］.北京：中國建筑工業(yè)出版社，2010.［3］GB 50010—2010 混凝土結(jié)構(gòu)設(shè)計(jì)規(guī)范［S］.北京：中國建筑工業(yè)出版社，2011.［4］扶長生，劉春明，李永雙，等.高層建筑薄弱連接混凝土樓板應(yīng)力分析及抗震設(shè)計(jì)［J］.建筑結(jié)構(gòu)，2008,38(3):106-110.
